I have the same problem. Dell told me that the "lamp driver has gone bad" and that you cannot fix it. If it's under warranty (as mine is for only 19 more days!) they will ship a replacement projector. Otherwise, the bill would be $730 and I would have bought a new projector instead.

Had the same symptom. After disassembling I noticed that one cap (10V 3300uF) in the power supply circuit was boiled. (the top was domed out). I replaced it with 2200uF for testing (because i didnt have another one at hand) and everything worked fine again :))

1. Red status LED, self-diagnosis error 44,
check for open F9A06 on the Power PCB part # 283P128050 on the Power PCB 2. Red
lamp LED, self diagnosis error 34. Check for 5-volts DC at J-9 connector pin 1
and 2 on the Engine Driver PCB if missing replace the Power PCB part #
930B921002 3. LED stops blinking after 70 seconds of plug in but will not power
on. This model is equipped with a keyboard lock feature, this can be mistaken as
a no power condition. To unlock the keyboard press and hold the "menu" button on
the front panel for 10 seconds 4. LED stops blinking after 70 seconds of plug in
but will not power on. Check for 3.2 volts DC at connector LE pin 3 and 4 on the
Control PCB, if low suspect problems with the switches/buttons on the Control
PCB part # 935D776001 5. LED stops blinking after 70 seconds of plug in but will
not power on. Keyboard is not locked and key inputs at connector LE pin 3 and 4
check good. Suspect the E2P PCB part # 934C121001 6. (LED does not stop blinking
after plug in) Disconnect the USB connector from the card reader to the front
from the Chassis, if the LED stops blinking after 70 seconds replace the Card
Reader part # 299P271010. 7. (LED does not stop blinking after plug in)
Disconnecting the USB connector from the Card Reader did not help. Remove
connector FC from the FMT PCB and plug the unit in, if the LED stops blinking
after 70 seconds with FC removed suspect a problem on the FMT PCB (part #
930B924002), if the LED keeps blinking with connector FC removed suspect a
problem on the DM PCB (part # 934C116002). 8. (LED does not stop blinking after
plug in) On the DM PCB (part # 934C116002) check C81A2, C81A3, C81B3 and C81B4
(1000 UFD, 16V, 105C), if any are bad, replace all of them with part #
181P734030 (680 uFD, 16V, 105C). See Service Tip VS-78A 9. (LED does not stop
blinking after plug in) On the FMT PCB (part # 930B924002) check C8F19, C8F21,
C8F22, and C8F27 (16V 1000 UFD 105C), if any are bad, replace all of them with
part # 181P734030 (680 uFD, 16V, 105C) See Service Tip VS-78A

Have you actually replaced the lamp first? A weakened lamp will often cause random shutdown or troubles during initial firing of the lamp. The LG televisions will be just the bulb itself not the complete lamp assembly. It's not hard to replace the bulb as long as you first allow the TV to cool down for a minimum of an hour. Then you will want to handle the lamp with latex gloves on to avoid getting oils from your skin on the bulb. You can find your bulb replacement at http://www.partstore.com

If the second light is blinking to orange or red, that is usually the lamp indicator light on an LG DLP tv. That indicates your bulb needs replaced, or something surrounding the bulb has failed (like the cooling fan for the bulb for example) IF you have a spare bulb handy, I'd replace the bulb, keeping in mind if you touch any part of a new bulb with your bare hands, you just cut the life of the bulb by more then half.

I looked up the manual online - after you replace the bulb, you need to reset the bulb life timer. Using the TV remote push the menu button, SETUP menu, select the lamp reminder option to reset the hours to zero. That might help the status indicators.

My Panasonic PT-50LC13 when turned on has a green light for a few seconds you can hear the fans turn on and then you have a yellow/amber light that starts to blink 8 times i have replaced the bulb and the door is closed any ideas?

I found the following suggestion on avsforum.com and it worked perfectly (going through the lamp door).

I'm a longtime lurker not much of a poster, but this happened to
me to yesterday. I used civicsixxx's advice and this works. However you
don't have to take anything apart. All I did was take out the lamp then
put your hand in carefully to the right and you'l feel the fan just
give it a spin and plug back in the light and the TV your good to go.
Hope this helps.

You really should give make & model number when posting, it helps us immensely, your lamp and possibly the ballast is bad, start with a new lamp first, odds are very good that it will fix your problem, can`t help more without manufacturer and model number, good luck, ps, order the original lamp, generics are junk and a waste of your money.
